What is constructed against solid wood floors
Laying plank flooring: instructions and tips from wood planking experts

Basic laying procedures
There are different methods of installing a plank floor. The sub-floor is decisive for this. At pur natur, we differentiate between the following two laying methods:
Lay the planks using screws
Lay floorboards using full-surface gluing
We recommend screwing the wooden planks where technically and functionally possible and sensible. On some surfaces - depending on whether it is equipped with or without underfloor heating - full-surface bonding makes more sense.
Lay wooden floorboards floating
»Floating installation« is often mentioned - this variant is used for some parquet or laminate floors. However, high-quality, solid wooden floorboards should not be laid floating. We understand the term in the context of solid wood flooring to mean laying the floor without a permanent connection to the immediate subsurface. So-called "cross battens" can also be laid floating, but the solid wood planks are screwed onto it.
Reasons against the floating installation of Solid wood flooring
Solid step feeling: When the wood is screwed or glued, a solid, valuable step feeling is created.
Rattle-free: A plank floor with large-format solid oak planks needs a firm connection to the sub-floor. Creaky floorboards are caused by the working of the solid wood floorboards with a floating installation. It can cause the wood to lie hollow and / or consequently to rattle.
Less work behavior: If a solid wood plank is laid "freely" and it has no attachment to the sub-floor, then it works freely. This means that it may warp. When screwing or gluing, the wood is “held in place” and therefore exhibits significantly less work behavior.
Lay solid wood planks using plank screws
In contrast to tiles, for example, wooden coverings can be screwed together. The laying process is divided into two variants:
- Concealed screw connection
- Screw connection from above
Concealed screw connection
In contrast to tiles, for example, a board can be screwed on. The laying process is divided into two variants:
- Concealed screw connection
- Screw connection from above
Concealed screw connection
Laying wooden planks in this way is very common and is used with a selection of up to 300 mm width.
Schematic representation of concealed screw connection
With concealed screwing, you can only work from wall to wall. You can't start in the middle of a room. This means that you start with the groove side of the products on one wall and then pass through the room to the other side of the wall. The floorboard screws are screwed into the subsurface by the spring at an angle of 45 degrees. Make sure that you do not overtighten it, otherwise there is a risk that the spring will tear off.
Carefully screw the last piece tight with a cordless drill with integrated torque limiter. The screw is hidden by the next board. Small screw heads are important so that the groove of the next real wood plank can be easily placed on the tongue. The screw head must also sink into the wood as far as possible. In order to lay the wooden planks in a stable manner, they must be fastened every 40 to 60 cm. The first and last wooden planks must also be screwed through on one side from above, otherwise the plank would only lie on top and could "rattle".
- quick and easy
- no visible screws
Screw connection from above - Lay the plank floor
Laying a floor made of planks using this method is used for very wide wood. It is ideal for board widths of 350 mm or wider. Even with narrow solid wood planks from z. B. oak or Douglas fir, this installation method can also be used.
A 15 mm Forstner bit is used to drill a 6 to 10 mm deep hole at a specific distance from both board edges. Then pre-drill with a 3 to 4 mm wood drill (not into the substructure!). Then the board is screwed with the appropriate board screws. You will receive perfectly matched screws with the purchase of your plank floor.
The distance between the screws is usually determined by the distance between the bars. The maximum distance is 100 cm with a thickness of 35 mm. If you lay solid wood planks on OSB boards or screw with chipboard, a flat spacing of 50 cm is recommended. For example, for oak boards with a thickness of 16, 21 or 22 mm, the plug hole is only drilled 6 mm deep so that the board is strong enough to hold the screw.
|Board width||Distance from the edge of the board|
Table: Edge distances
The following wood spacing should be understood as a guideline.
|Wood species||construction||Strength||Private||Business||Museums or similar|
|Douglas fir||3 layer||21mm||50cm||45cm||40cm|
|28 / 30mm||80cm||70cm||60cm|
Table: recommended beam / screw spacing
After the floorboard has been laid and screwed in, a suitable wooden plug with waterproof glue must be glued into each hole. For this purpose, wood glue is put into the hole and the stopper is hammered into the hole with a hard rubber hammer. Now sand off the excess with a grinding machine. Matching wooden plugs in Douglas fir and oak are available from us.
Full-surface bonding of wooden planks
In addition to screwing wood, full-surface gluing is a common method of fastening the plank floor.
In the installation process of full-surface gluing, special parquet adhesives are used to glue the entire surface to the sub-floor. This method is suitable for flat substrates such as Fermacell or OSB boards. Use only recommended adhesives and primers for this.
All pure natural solid wood planks are suitable for full-surface gluing. If you have any questions, please have the article number ready and make sure that cookies have been activated in your browser.
Screed: You should pay attention to this if you Buy wooden floorboards and embarrassed
Full-surface gluing is the best solution if a screed forms the sub-floor and you want to lay the plank floor directly on it. This is typical for new buildings or renovations. When renovating and building, it does not matter whether it is a screed with or without underfloor heating. This process also creates impact sound insulation.
It is important to adhere to the preconditions for full-surface bonding:
- The ground is dry
- The substrate has the necessary evenness (+ -2 mm on a 2 m straight edge)
- The maximum permitted residual moisture of the screed is: <1.8% CM for cement screeds, <0.3% CM for anhydride screeds
- Very good footfall sound insulation.
- Low installation height.
- Very high strength thanks to premium adhesives. Nevertheless, a minimal amount of work on the wood is possible.
- Valuable, very solid step feeling.
- time-consuming and costly dismantling.
- Wood is completely destroyed.
- Damage to the sub-floor is unavoidable.
A detailed step-by-step guide for laying the wooden planks would go beyond the scope of this article. For the installation instructions »Full-surface bonding«, please contact us as part of your project.
An overview of FAQ related to this:
- Substrate preparation and testing, if necessary application of the primer
- Prepare / cut the wooden planks
- Apply the adhesive to the screed with the help of the right notched trowel
- Inserting the floorboards from z. B. oak in the adhesive bed, brace if necessary
- Weighting down the floor
- Setting time
The floors are resilient after a setting time of approx. 24 hours. The surface treatment is possible after 48 hours when using PU, SMP or SPU adhesives. Do not walk or strain during the dry season.
Laying variants for the oak floor
Before installing a wooden floor, you should decide whether you want to lay the wooden planks with or without visible joints. Solid wood planks from 350 (plank width: mm) must be laid with a visible joint. As visible joints, we mean deliberate joints between the real wood planks, which are incorporated when the floor is laid. The joint size between the floorboards is between 1.0 and 2.5 mm.
We recommend the following joint sizes depending on the board width:
|Board width||Recommended joint size|
|Up to 200mm||1.0mm|
Table: Recommended joint size depending on the board width
Products: Solid wood plank - wooden floor with visible joint
This installation variant is required for a plank floor with solid floorboards from 350 mm wide. Laying with a visible joint is not recommended for all narrow wooden floors or herringbone patterns. It is particularly suitable for a floor with room-length pieces of wood.
Laying with a visible joint is particularly suitable for a floor with room-length pieces of wood.
Floor board laid with room-length Douglas fir floorboards with exposed joints
Laying wooden planks: do you have to build in a gap?
Spacers with a long profile should be used to ensure that the joints between the wooden planks are adhered to precisely, so that there are no pressure points when the wood is tensioned. We recommend aluminum T-profiles with a length of at least 30 cm, clamped between the solid boards at a distance of approx. 50 cm.
Lay floorboards without visible joints
Many architects and builders want a wooden floor to be laid without visible joints. This variant is technically possible for all types of planks. Furthermore, it can generally be turned away on all 3-layer floors from pur natur, regardless of the width.
»Pur natur also recommends laying the floor without a visible joint for planks of falling lengths.«
